Complete and thorough inspections should be done on a routine,
periodic basis. The interval between inspections and scope of the
inspections will depend on the conditions of use. This interval must
not exceed 1 year.
All mountings and enclosures should be visually examined for any
condition that may affect mounting integrity. A complete inspection
should include, but not be limited to, looking for these types of
damage to DSA Series loudspeakers and parts:
bends
breaks
broken parts
corrosion
cracks
cracks in welded joints
deformation
DANGER: Should any of the above listed types of damage exist,
immediately remove the affected part from service for repair or
replacement. If there is any question about the integrity or capability
of any mounting or rigging part to perform its intended function, it
must be immediately removed from service for repair or replacement.

Listening tests and/or formal measurements should be done
periodically. The interval between such tests will depend on the
frequency of system usage and the conditions of use. All transducers
should be tested for functionality and proper performance.
Careful listening will usually reveal transducer and/or enclosure
problems in the form of distortion, buzzes, rattles, or non-function.

The sides and rear of the enclosure function as a heat sink for the
internal amplifiers. Because of this, they must remain relatively free of
dust and dirt to ensure good heat transfer to the surrounding air. If
these surfaces need cleaning, use a vacuum and/or damp cloth to
remove any dust or dirt.
CAUTION: To avoid damaging the exterior finishes do not use cleaning
solvents or abrasives.
